JACOB H. HOBWITZ, OF NEW YORK, N. -Y.

FILE-BOOK, &e.

To all whom it may concern:

Be it known that I, Jason H.1IORWITZ, a citizen of the United States,residing in the borough of the Bronx, city, count and State of New York,have invented certain new and useful Improvements in File-Books, &.c.,of which the following is a specification.

My invention is designed to alford a simple, inexpensive device for usein filing, preserving and rendering accessible for exhibition orreference various articles, such as letters, prescriptions, samples,pictures and the like, and it consists in the construction andarrangement of parts hereinafter described and claimed specifically.

In the accompanying drawings, Figure 1, is a top view of my improvedfile book with portions broken away; Fig. 2, is a cross section of acentral portion thereof; Fig. 3, is an isometrical view of one of thebinding and spacing strips; Fig. 4, is a section upon plane of line 4;4Fig. 1; Fig. 5, is a top view of a central portion of the book open andbroken away, showing a modification; Fig. 6, is a section upon plane ofline 9-9 Fig. 8.

B represents a solid, rigid backing of wood or any other suitablefibrous material, to which the usual side boards or covers I), b, may beattached if desired, although the covers are not indispensable to myinvention.

In the drawings, for convenience of illustration, the several signaturesS, are represented as consisting of only single folds of paper or othermaterial, it being understood that said signatures may contain anydesired number of pages, as may be found most expedient. Thesesignatures are each secured to the fiat surface f, of the back B, by oneor more metallic strips a. In securing the signatures S in position onthe fiat surface f', of the back, each signature is opened and placed inposition on said fiat surface f, and a spacing strip a, laidlongitudinally along the center or bight of the signature, the ends ofthe spacing and binding strip a, being then secured to the back B.

WVhile the binding and spacing strips a, may be of any desired shape andsize in cross section, I prefer to make them in the form of elongatedstaples as shown in the drawings,that is to say each with an elongatedmiddle or spacing portion a, having sharpened rectangular ends a", whichmay be driven into the back B. This form of Specification of LettersPatent.

Application filed May a, 1907. Serial No. 371,794.

Patented Jan. 19, 1909.

binding and spacing strip is by reason of its cheapness andsimplicityand the ease with which it may be applied, obviouslypreferable to the employment of strips secured in position by othermeans.

Obviously one or more strips a, may be used for each signature. Thus inFigs. 5 and 6, three relatively short staples a, a, a, are used inalinement,-one in the middle and one at or near each end of the bight ofthe signature. I prefer however to use a single staple for eachsignatureas shown in Fig. l, letting the ends project slightly beyond the edgesof the leaves, and securing the central portion of the strip a, by meansof a brad (Z, or equivalent, driven through a perforation in the stripa,the object of this intermediate attachment of the strip a, to the backbeing to prevent the possibility of arching or looseness of the centralportion of the strip, and also to prevent the withdrawing of the leavesof the signatures.

My improved file has many advantages over those heretofore known andused by reason of its simplicity, durability and convenience. It is notonly more effective but it is more economical of space in that the wholesuperficial area of each page is available for use. It is alsocomparatively inexpensive in structure.

That I claim as my invention and desire to secure by Letters Patent is,

1. In a book of the character designated, the combination of a rigidback of fibrous material provided with a flat inner surface, and asignature binding and spacing strip consisting of an elongated metallicstaple adapted to be laid longitudinally along the bight of thesignature and to have its sharpened rectangular ends driven into theflat side of the rigid back.
